The difference between <c: import url = "child.jsp" / "> and <jsp: include ...>

I know the performance difference between the next two

  • Include directive ( <%@ include file="test.jsp" %> ): This includes the contents of the file during the compilation phase, that is, when the page is converted to a servlet.

  • Include action ( <jsp:include page="test.jsp" flush="true" /> ): this includes the contents of the file in run-time-ie when the user makes a request for the page.

But what about the JSTL tag <c:import url="child.jsp" /> is this content included during the compilation phase or runtime?

Thanks!

It is included at runtime. And you can specify an absolute URL (you can enable html from third-party sites)

If you are talking about <jsp: include /> This tag includes jsp runtime. That way you can use it recursively.

About c: include ... is a tag, so (I think) this is the execution step ...

By default with import c: import of the imported resource is included in the JSP string at run time. Although you can also access the resource as a String object or a Reader object.

URL can be absolute (any external web application) or relative (contextual)
